Groovy Programming Fundamentals for Java Developers

Description

In this course, we take you step by step through the most common features and programming idioms of the Groovy programming language, enabling you to supercharge your developer productivity by harnessing the power of Groovy's lightweight and succinct programming syntax.

There are not many technologies that can brag about staying relevant for more than 30 years. Java is one of those technologies that is not only staying relevant but also evolving with time. However, in Java, due to verbose and complexities in coding, developers started using different platforms and languages to counterfeit this downside. Apache Groovy is the number one go-to language when it comes to knocking up quick scripts to automate drudge work and even for writing full-scale applications (using other frameworks such as Grails and Griffon). Groovy is predominantly seen today in Jenkins pipelines scripts and in Gradle build scripts, but this really underplays its power and versatility, as we'll see in this course. You will learn many exciting features of Groovy and see how it reduces execution time with its lightweight syntaxes. This course will teach you how to set up Groovy, install it, and create Groovy projects in the IDE. Then you'll be exploring the Groovy toolset and using the Groovy console to execute Groovy code. Moving ahead, you'll learn common Groovy operators that form the cornerstone of its powerful syntax. You will then learn how to use regular expressions and capture groups to parse and extract strings. You'll also look at Groovy collections and the enhancements delivered by GDK (Groovy Development kit). Finally, you'll be filtering and transforming collections in Groovy with Groovy's powerful closure mechanism and much more. By the end of this course, you will learn Groovy's features and start using them in your day-to-day activities with ease.

Learn how to iterate and search through collections in Groovy

This course is best suited for the beginner- to intermediate-level Java developers who want to accelerate their existing Java coding tasks using Groovy.

Interested developers in other programming languages who want to write programs that can execute on the Java Virtual Machine, without having to use Java will also find this course useful.

Working knowledge of the Java programming language is assumed as a prerequisite, although the course can be used without this knowledge (but it will make more sense and be easier for a Java developer to understand).

This course will take you step by step through the most common features and programming idioms of the Groovy programming language.
